Abstract
A method for performing a pressure test on a tank (e.g. hydrogen tank) and a filling apparatus is disclosed. The tank is connected via a tank valve to a tank feed line which has a first valve for shutting off the tank feed line, wherein during the pressure test prior to the tank being filled through the tank feed line a flow of medium, with the first valve closed, is directed into the tank via a bypass line bridging the first valve, wherein the flow of medium is throttled in the bypass line such that a tank feed pressure acting on the tank valve rises in a controlled manner, wherein the tank valve opens particularly when the tank feed pressure exceeds the pressure prevailing in the tank.
